TRAP-NEST.

Specification of Letters Patent.

Patented Sept. 19, 1916.

Application flied April 28, 1918. Serial No. 94,163.

'1' all whom it 1h (13 concern Be it known that I, Banner I-I. OsNNINo,a citizen of the United States, residing at I niontown. in the .countyof \Vhituian and State of Washington, have invented certain new anduseful Improvements in Trap- Ncsts; and I do hereby declare the followinto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same. 'i

The primary object of this invention is to provide a novel type oftrapping meclmnism designed to be associated with a nest so as toprevent the escape of a hen from the nest when it is desired to confinethe hen thereon, and also to prevent the entrance of other poultry whilethe nest is being occupied.

Another object of the invention is to provide a trapping mechanism forcarrying out the above object, whiclrwill be of simple and durableconstruction and eiiicient in oporation.

Other objects will up ear and be better understood from that em odimentof my invention of which the following is a specification, referencebeing had to the accompanying drawings forming a part thereof, in which:

Figure 1 is a front elevation of the trapping mechanism for the nest,showing the trapping mechanism in a position to admit of the passage ofthe poultry through the entrance opening in tie stationary element. Fig.2 is a view showing the door locked in operative position, Fig. 3 is aview showing the locking mechanism for the door being moved to operativeposition during the closing of the door, Fig. 4 is a detail verticalsection, taken on the line 4-4 of Fi 3, Fig. 5 is a front elevation ofthe nest, s W- ing a modified form of locking mechanism for the door,Fig. 6 is a horizontal section, taken on the line (i6 of Fig. 5, Fig. 7is a front elevation of another modified form of trapping mechanism, andshowing the door unlocked, Fig. 8 is a front elevation of theconstruction shown in Fig. 7 with the door locked in closed position,Fig. 9 is a section taken on the line 9-9 of Fig. 8, Fig. 10 is a topplan view of the locking mechanisms shown in Figs. 7 and 8.

Referring to the drawings in detail, the letter A designates astationary element which is ada ted to form one wal of a nest, and isprovit ed with an entrance opening 13,

the said entrance opening B being designed to be partially closed bymeans of av movable element 1, which is adapted to provide a door, andincludes an elongated vertically disposed body having its u )per endprovided with an extension 2, ocated to one side of the door, and whichextension has pivotal connection with the wall A by means of a pivot pin3. The door 1 only partially closes the opening B, and by virtue of themanner of pivoting the door to the wall, the door will gravitate toclosed position u )Oll being released from open position. he door hasthat side edge which extends across the opening B provided with asemicircular cut-out portion 4, which admits of the poultry insertingtheir heads through the opening B and moving the door to open positionwhen the door is unlocked. In Figs. 1 to 6, inclusive, the lower end ofthe door 1 is operable through a guide 5 mounted on the adjacent wall ofthe housing, and which serves to )rcvent outward movement of the loweron of the door 1. In Figs. 1 to 4, inclusive, the door 1 isprovidedadjacent its u )PUI' end, with a substantially V-shaped slothaving a supporting branch 6, and an upwardly and inwardly curved uidingbranch 7, the a )per end of the gui( ing branch 7 communicating with a.downwardly directed locking notch 8. Another movable element consistingof a rod 9 has one end pivoted to the wall A, as shown at 10, and itsopposite end bent angulurly to provide a locking element or tongue 11.lVhen it is desired to unlock the door so as to admit of the assage of ahen through the opening B tlie rod 9 is raised so that the tongue 11will lie in the branch 6 of the slot and he supported therein, as shownin Fig. 1. During the mssage of the hen through the opening B, t 1e door1 will be swung on the pivot 3 causing the tongue 11 of the rod 9 todescend to the lower end of the branch (3, as shown in Fig. 3. WVhen thedoor is released and moved to closed .osition, the tongue 11 will bedrawn upwarc ly in the branch 7 and enter the notch 8 and lock the dooragainst movement.

In the modification shown in Figs. 5 and 6 the rod 9 has one end pivotedto the door 1 at 10' and its opposite end operable in a horizontallydisposed and substantially V- shaped slot 12, formed in the wall A at apoint spaced from the door opening B and the apex of the V-sha ed slot1s enlarged, as shown at 18, and the iower branch of the V- shaped slotcommunicates with the locking notch 14. In this construction the tongue11 on the rod 9 is placed in the upper branch of the slot 12, when thedoor is set for movement, and upon movement of the door to open positionthe tongue 11 will travel toward the a ex end of the V-shaped slot anddescend and aline with the lower branch of the slot so that durin theclosing of the door the tongue 11 will travel toward the inner end ofthe branch and enter the looking notch 14 and lock the door againstmovement.

In Figs. 7 8, 9 and 10, instead of employing the guide the up er end ofthe door is extended approximate y to the upper end of the stationaryelement or wallA and provides means for protecting the lower end of thedoor from being pushed outwardly. In the construction shown in thesefimres an elongated flat arm 15 is substitutec for the rod 9 and has oneend ivoted to the door and its opposite end en arged, as shown at 16,and provided with a substantiall V- shaped slot having a straight branch1 and a slightly curved branch 18, the free end of the latter branchcommunicating with a notch 19 which extends substantially at an acuteangle to the curved branch 18 and has its outer end enlarged, as shownat 20. A. stud 21 is mounted on the wall A, at a point spaced from theopening B, and is adapted to be interchangeably received by the branches17 and 18 of the slot. The head 22 is mounted on the outer end of thestud 21 and engages the outer side of the arm 15, and spacing plates 23are interposed between the arm and the wall A and are secured in placeby means of the stud 21. When the arm is in the osition shown in Fig. 7,and the stud 21 is received b the strai ht branch 17 of the V-shaped 30t in the oor, the door will be unlocked and can be opened by the oultryin the manner before described. Vhen the door is being moved to openposition the arm 15 will be moved upwardly so as to present the apexCopies of this pstent may be obtained tor five cents each, by addressingthe end of the V-shaped slot to the stud 21. When the door is returningto closed position the stud 21 will enter the branch 18 of the V-shapedslot and when the door has reached its lowermost position the stud 21will aline with the notch 19 so that the enlarged end of thearm willdrop and cause the enlarged end 20 of the notch 19 to receive the stud21 so as to lock the door against movement.

Having thus described my invention what I claim as new, is:

1. A trapping structure for a nest comprising a stationary element and apair of movable elements, one of the latter elements having pivotalconnection with the firstinentioned element and adapted to obstructpassage to and from the nest, one of the elements having a V-shaped slottherein, one wall of one of the branches of the slot having a notchtherein, and means carried by the other of the elements and constantlyengaged in said slot during movement of the obstructing element tooperative or inoperative osition and directed by one branch of the s 0tinto the notch after the obstructing element has moved to operativeposition.

2. In a trapping structure for a nest, the combination with a wallhaving an entrance opening therein and a door for closing the opening,of an arm having one end connected to t 1e door and its opposite endprovided with a V-shaped slot, one of the branches of the slot havingone wall thereof )rovided 'with a notch, means carried by t e walls adated to be received by the other branch of t e slot during opening of thedoor and to be received by the first-mentioned branch during closing ofthe door and to engage in the notch when the door has been moved toclosed position.

In testimony whereof I ailix my signature in presence of two witnesses.
